1. Brief introduction
NF series dry sand making production system streamlines crushing, shaping and grading. Its key patented technology lies in USF crusher, which is newest crusher with grading functiondeveloped by NFLG and Japanese Kemco. The crusher is capable to carry out crushing and grading independently. Its unique design also takes utility, economic benefit and environment protection into consideration, meeting stringent requirements of potential customers.
2. characteristics

Solidity ratio is an important index to judge shaping effect of aggregate particle. The USF crusher removes sharp edge of particle after crushing, improving its shape. No matter there is coarse or fine raw material, the crusher shows excellent properties: high efficiency, high solidity ratio and stabile particle size.
